North Durras Reef Wind Statistics, Janeiro averages since 2006

The graph illustrates how frequently and how strongly the wind blows from different directions through a typical January. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2868 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to North Durras Reef, located 24 km away (15 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.

According to the model, the most common wind at North Durras Reef blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at North Durras Reef. Converseley, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average January, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (2 days each January) and blows offshore 16% of the time (5 days in an average January). During a typical January wind stronger than >40kph (25mph) was expected for only a single days at North Durras Reef

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
